var assert = require('assert');
var zipmap = require('zipmap');
var keys = ['a', 'b', 'c'];
var vals = [1, 2, 3];
var map = zipmap(keys, vals);
assert.deepEqual(map, { a: 1, b: 2, c: 3 });Or use an array of objects
var objs = [
{ key: 'foo', value: 'bar' },
{ key: 'hi', value: 'bye' },
];
var out = {
foo: 'bar',
hi: 'bye'
};
var map = zipmap(objs);
assert.deepEqual(map, out);or use an array of pairs
var pairs = [
['foo', 'bar'],
['hi', 'bye']
];
var out = {
foo: 'bar',
hi: 'bye'
};
var map = zipmap(pairs);
assert.deepEqual(map, out);Changelog
